General Information
Term ventral disc ID (Ontology) GO:0097597 (Gene Ontology)
Definition Specialized organelle found in Giardia species (trophozoite stage) and characterized by a spiral array of microtubules and microtubule-associated structures including dorsal microribbons and crossbridges. The edge of the ventral disc narrows into a lateral crest. The ventral disk mediates mechanical attachment of the trophozoite to the host's intestinal wall, and contains the contractile proteins actinin, alpha-actinin, myosin, and tropomyosin working towards contraction of the disk involved in adherence.[ ISBN:9780124260207 PubMed:11432808 PubMed:4777416 PubMed:5961344 ]
Also Known As "ventral adhesive disc"
